OIL-BURNER.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed zan 2s, 1.915. seria no. 42,495.

To all whom it may concern:

Be it known that I, BERNARD Fnnsn, a citizen of the United States,residing at Lemoore, in the county of Kings and State of California,have invented certain new and useful Improvements in Oil-Burners, ofwhich the following is a specification.

My invention relates to improvements in oil burners, and is animprovement upon the oil burner for which patent was granted to me,December 1, 191-1, Number 1,119,591.

One object of my invention is the provision of an oil burner wherepetroleum or distillates thereof are converted into gas before ignitiontakes place. The gas generated in the known burners of this kind, isunder more or less pressure which causes the carbon residue in theheated generator to become hard, and causes the small openings, fromwhich the gas escapes to clog and gradually close.

Another object of my invention is the provision of an oil burner whicheliminates these objections by producing a gas generator that allows thegas to escape freely therefrom without the gas becoming ignited therein.The advantage I obtain thereby is that the sediment formed in thegenerator does not harden, but is of a soft spongy consistence easilyremoved, and allows the gas to expand before being ignited.

Another object of my invention is the provision of an oil burner inwhich the oil is superheated and converted into gas before entering thegenerator.

Another object of my invention is the provision of an oil burner inwhich the mixture of air with the gas produces a perfect combustionthereby being economical in fuel.

Another object of my invention is the provision of an oil burner for thepurposes stated, which will be inexpensive to manufacture, simple ofconstruction, durable and practical from every point of view.

With these objects in view my invention consists of an oil burnerembodying novel features of construction and combination of parts forservice substantially as shown, de-

tional view, and Fig. 3 is a detail view of the distributer or burnerhead.

In the drawings in which similar letters denote similar parts throughoutthe several vlews, the letter A, designates the casting having the lugreceiving openings B, to receive the lugs C of the tapered burner heador distributer D, projecting into the mouth or openlng E, of thecombustion chamber F, of the casting. Integral with the casting A, 1sthe 011 conductor G, having the threaded end H, to receive the oil feed,and the threaded end H, receiving the threaded end J of the pipe J.Attachedto the pipe J is the elbow K receiving the vertical pipe L,which pipe is in the path of the flame, thereby causing the oil to besuperheated and converted into gas. Connected to the top of the pipe Lis the elbow M, leading from which is the horizontal pipe N, connectedto the pipe N, by the union 0.

The wedge-shaped burner head or distributer D, has the two threadedopenings P, in order that the interior of the distributer may becleaned, said openings being closed by the threaded plugs P, and thedistributer is further provided with a threaded opening Q, in its top toreceive the nipple elbow Q, connected to the pipe N. Thus it will bereadily seen that the oil enters the conductor G at H, thence throughthe pipe J, into the vertical pipe L, where it is converted into gas bythe heat from the flames. The gas then passes through the horizontalpipe and through the nipple elbow Q, into the distributer. Thedistributer D has its inner end tapered and has the slot opening B,through which the gas passes into the chamber F in a spray.

From the foregoing description taken in connection with the drawings theoperation of my oil burner will be readily understood,

and it will be apparent that the oil is fed to the conductor on theunderside of the casting, thence through the heating pipe where it issubjected to great heat and converted into a vaporous gas, and is thenfed to the distributer or burner head and into the generating chamber ofthe casting, drawing in suflicient air to produce a highly inflammablegas which is ignited at the proper location to insure the highest degreebf efficiency.

.It will be noted that the several parts of the burner are easilyaccessible for the purpose of cleaning, removal or repair; also that theconstruction is simple, strong and durable; inexpensive of productionand absolutely reliable, efiicient and practical.

I claim:

1. An oil burner, consisting of a casting provided with an oil supplychannel and mixing chamber, an oil heating and conducting pipe leadingfrom said oil supply channel, said conducting pipe passing through thepath ,of the flame, whereby the oil is converted into a vaporous gas bythe intense heat, said casting being provided at its mouth withrecesses, and a burner head or distributer connected to said pipe andprovided with lugs engaging said recesses for securing said burner headin proper relation.

2. An oil burner, consisting of a. casting provided with an oil supplychannel and mining chamber, an oil heating and conducting pipe leadingfrom said oil supply channel, said conducting pipe passing J ll-rough(the path of the flame, whereby the oil is converted into a vaporous gasby the intense heat, said casting being provided at its mouth withrecesses, and a burner Oqpies of this patent may be obtained for fivecents each, by addressing the commissioner of Patents, wesliins ain- 9-
